CAR-BRAKE.

sPECIFICATION forming part of Letters Patent N 0. 729,358, dated May 26,1903. Application filed September 3, 1902. Serial No. 121,936. (Nomodel.)

To all whom it may concern: 1

Be it known that I, CHARLES A. KLEINER, a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedOar-Brake, of

The invention consists in the novel con struction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forlninga part ofthis specification, in which similar characters of reference indi catecorresponding parts in all the figures.

Figure 1 is a bottoinplan view of a portion of a car and the wheels ofone truck, together with the ordinary and auxiliary brakes applied tosaid wheels. Fig. 2 is a vertical section taken practically on the line2 2 ofFig. 1,

and Fig. 3 is a side elevation ofone of the;

auxiliary brake-shoes.

A represents the bottom portion of a car; B, the wheels of a trucknearest an end of the car carried by the usual axle B, and C and Crepresent hangers which are secured to the bottom portion of the car,extending downward therefrom at opposite sides of the axle B adjacent tothe wheels B, a

D represents the ordinarily-located brakeshoes adapted for engagementwith the outer tread portions of the car-wheels; but the brake-shoes Ddifier from the ordinary brakeshoes in that they each consist of a body11, having a concaved surface facing the wheels, and a bearing-surface10, conforming to the concaved surface of the body and provided withdovetail lugs 12, which enter correspond ingly-shaped recesses in thebody, enabling the braking-sections of the shoes D to be readily removedfrom the body and replaced by others should they become unduly worn. Thebrake-shoes D are connected by a brakebar 13, and this brake-bar hassliding movement in horizontal stays 14 at the bottom por tion of thehangers O, and springs 15 are attached to the brake-bar 13 and to thehangers, acting to normally hold the brake-shoes D rom engagement withthe wheels B.

'which'receive dovetail projections 19 from a brake-surface 20, adaptedfor direct engage- 'ment with the tread of a wheel; and at the bottomportion of each auxiliary brake-shoe D, which bottom portion is flat orhorizontal, a longitudinal dovetailed recess 18* is made, adapted toreceive a dovetail projection from a bottom bearing surface 20, whichbearing section 20 at its outer or forward portion is provided with an-upwardly-extending section 21, fitted to meet the back of the concavedbraking-section 20, Under this construction it is obvious that both ofthe braking-surfaces of the auxiliary shoe D can be removed and quicklyreplaced, thus economizing in the wear of the rolling-stock.

At the rear or inner edge of each auxiliary brake-shoe D an upwardly andoutwardly extending horn 22 is formed, and on these horns of theauxiliary brake-shoes a brakebar 23 rests and is secured, the saidbrake-bar having sliding movement in slots 24:, produced in the hangersC, which slots extend downward and outward, as is shown in Fig. 2, sothat when the brake-bar 23 is at the upper portion of the slots 24 theauxiliary brakeshoes D will be out of engagement with the wheels B andwith the track; but when the brake-bars 23 are drawn down the inclinedslots 24 the auxiliary brake-shoes D are brought into action, bearingagainst the wheel and simultaneously bearing against the tread of thetrack. The auxiliary brake-shoes D are normally held out of brakingaction by a spring 25, attached to the brake-bar 23 and to the hangers0. Both sets of brakes are simultaneously operated through the medium ofa single brake-shaft 26, located at an end portion of the car andprovided with the usual ratchet and pawl.

The brake-shaft 26 extends down and is journaled at the bottom portionof a cage 27, and at the lower portion of the brake-shaft 2G flanges 28are formed. Between these flanges 28 an end of a main operating-chain 29is secured to the brake-shaft 26 to be wound around the same. This chainextends from the said brake-shaft in direction of one side of the car toabout a central point between its sides, and is then passed over apulley 30, supported at the lower end of a hanger 31, securred to thebottom portion of the car. The main brake-chain 29 is then carried indirection of the axle B, and adjacent to said axle is passed upward overa pulley 39, journaled between hangers 33, extending down from thecentral portion of the car, as is shown in Figs. 1 and 2, and then thesaid main brake-chain 20 is carried to an'engagement with the centralportion of the brake-beam 13. This main chain acts directly on the mainbrake-beam 13 to apply the main brake-shoes D. The auxiliary brake-shoesI) are simultaneously applied however, by connecting chains 33 to thebrake-bar 23 at each side of its center and conmeeting these chains witha single chain 34, which chain Si is carried outward and connected withthe main chain 29 at a point between the central guide-pulley 32 and theouter end of the car, and the said chain 3% from the auxiliary brake isthen continued to the brakeshaft 26 over the pulley 30 or an auxiliarypulley to an attachment to the drum on the brake-shaft, as is shown inFig. 2. The continuation of the chain 34 insures the brake workingshould the chain 29 be damaged, since there is a double connection withthe brakeshaft.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a ear-brake, a shoe having a concavedlongitudinal side braking-section detachably connected to thebody-section and adapted for engagement with a car-wheel, and a bottombraking-section adapted for engagement with a rail, which bottombraking-section meets and fits with tight and uninterrupted connectionwith the side braking-section,

one section thereby bracing the other and constituting a lock, one forthe other, in direction of the thrust, the bottom braking-sectionbeinglikewise removably attached to the body portion of the shoe, thetwo braking-sections of the shoe constituting a continuous wheel andsurface brake, as shown.

2. An auxiliary brake-shoe adapted for engagement with a wheel andsimultaneously with a rail, the said brake-shoe comprising a body havinga concaved surface provided with dovetail recesses therein, adapted toface a wheel, a ln-aking-section adapted for engagement with a wheel,provided with dovetail projections adapted to enter the dovetailrecesses in the body, ahorn projected from the longitudinal edge of theshoe opposed to its braking edge, the said shoe being likewise providedwith a straight bottom surface having a dovetail recess therein, and astraight braking-section for engagement with a rail, having a dovetailedprojection therefrom to enter the dovetail recess in the bottom of thebody of said shoe, the two braking-sections being brought together atthe working face of the shoe, one having bearing on the other asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
